RELATED APPLICATION

This application is based upon prior filed copending U.S. Application No. 62/421,552 filed Nov. 14, 2016, the entire subject matter of which is incorporated herein by reference in its entirety.

TECHNICAL FIELD

The present disclosure relates to the field of supercritical extractor systems, and, more particularly, to supercritical CO₂ extractor systems and related methods.

BACKGROUND

The process of supercritical fluid extraction (SFE) comprises separating one component (i.e. the extractant) from another (i.e. the matrix) using supercritical fluids as the extracting solvent. A supercritical fluid comprises a substance at a temperature and pressure respectively above the critical temperature and the critical pressure, i.e. the critical point. In other words, a state where distinct liquid and gas phases do not exist.

A common supercritical fluid used in SFE is carbon dioxide (CO₂). In essence, in CO₂ SFE, the CO₂ is used as a solvent for the matrix. In a typical CO₂ SFE system, the SFE system includes an extractor receiving the matrix and supercritical CO₂, and an evaporator producing the extractant and waste CO₂. A typical drawback to earlier CO₂ extraction systems was that they were largely stationary and bulky. Accordingly, extraction applications may require substantial investment into equipment and maintenance. Also, some agrarian applications may not be suitable for this type of permanent installation.

SUMMARY

In view of the foregoing background, it is therefore an object of the present disclosure to provide a supercritical extractor system that is efficient and mobile.

This and other objects, features, and advantages in accordance with the present disclosure are provided by a supercritical extractor system comprising a supercritical fluid reservoir configured to store a supercritical fluid, and a supercritical fluid pump coupled to the supercritical fluid reservoir. The supercritical extractor system includes a plurality of extractor chambers coupled to the supercritical fluid pump and configured to receive a matrix for an extraction process and the supercritical fluid from the supercritical fluid pump, and a plurality of evaporator chambers coupled to the plurality of the extractor chambers and configured to output an extractant from the matrix. Each evaporator chamber comprises a body defining a cavity therein, at least one cone within the cavity, and a plurality of arms coupled between an inner surface of the body and the at least one cone. The supercritical extractor system includes a condenser coupled between the plurality of evaporator chambers and the supercritical fluid reservoir, and a controller coupled to the supercritical fluid pump, the plurality of extractor chambers, and the plurality of evaporator chambers and configured to monitor at least one characteristic during the extraction process. Advantageously, the supercritical extractor system may have a smaller footprint, thereby allowing for mobile deployment.

For example, the supercritical fluid may include supercritical CO₂. In some embodiments, the body may comprise a cylindrical body. The at least one cone may define an annular recess between the at least one cone and the inner surface of the cylindrical body.

Additionally, each extractor chamber may comprise a cylindrical body defining a cavity therein. The plurality of extractor chambers may comprise extractor chambers of differing capacities. The condenser may comprise a plate heat exchanger. The supercritical fluid pump may comprise a frame, a pump carried by the frame, and an electric motor coupled to the pump and carried by the frame.

Another aspect is directed to a method for making a supercritical extractor system. The method includes providing a supercritical fluid reservoir configured to store a supercritical fluid, coupling a supercritical fluid pump to the supercritical fluid reservoir, and coupling a plurality of extractor chambers to the supercritical fluid pump and configured to receive a matrix for an extraction process and the supercritical fluid from the supercritical fluid pump.
